how do tire treads actually generate more traction on flat surfaces?

691 views

I can understand in off-roading because they would actually bite into the ground and push against it, but if the road does not deform into the treads then wouldn’t it be better to have them slick for more surface area? why do race cars use slick tires and not consumer vehicles?

On road, they don’t. Race cars use slick tires during *dry* conditions. The treads on street tires are so that water has a place to go so that the other 80% of the wheel can get good traction on the road surface. Otherwise you run into “hydroplaning”, where the water can’t get out of the way and you get *zero* traction.
